1、(3b-2c)+[-4a-(c-3a)]-(3b-c)2、-a^n-(-5)a^n-1-2(a^n-1-3a^n)

1、(3b-2c)+[-4a-(c-3a)]-(3b-c)2、-a^n-(-5)a^n-1-2(a^n-1-3a^n)
1、(3b-2c)+[-4a-(c-3a)]-(3b-c)
2、-a^n-(-5)a^n-1-2(a^n-1-3a^n)

1、(3b-2c)+[-4a-(c-3a)]-(3b-c)2、-a^n-(-5)a^n-1-2(a^n-1-3a^n)
1、(3b-2c)+[-4a-(c-3a)]-(3b-c)
=3b-2c+[-4a-c+3a]-3b+c
=3b-2c-4a-c+3a-3b+c
=-4a+3a+3b-3b-2c-c+c
=-a-2c
2 -a^n-(-5)a^n-1-2(a^n-1-3a^n)
= -a^n+5a^n-1-2a^n+2+6a^n
=-a^n+5a^n-2a^n+6a^n-1+2
=8a^n+1
